Description

Technical Field

[0001] The utility model relates to the technical field of welding jigs, and particularly relates to a welding jig for automobile covers. Background Technique

[0002] Automobile covers generally refer to the covering plates or panels on parts such as vehicle doors, hoods, and trunk lids. These covers are usually part of the vehicle exterior, used to cover and protect the internal components of the vehicle, and also play a role in aesthetics and aerodynamic resistance. During the production of automobile covers, welding jigs are required to fix them and perform welding operations on the covers.

[0003] Most of the existing welding jigs clamp and fix the periphery of the cover, leaving a small welding space. It is necessary to adjust the position and fix it multiple times to complete the welding work. At the same time, the adjustability of the device is poor, and it is difficult to adapt to the fixation of covers of various sizes. Moreover, the edges of some covers are not straight. When the traditional welding jig fixes a cover with a non-straight edge, the fit with the cover surface is low, resulting in unstable fixation. For this reason, we propose a welding jig for automobile covers to solve the problems mentioned above. Content of the Utility Model

[0016] The beneficial effects of the present utility model compared with the prior art are:

[0017] This solution proposes an automotive cover welding fixture. By driving the lead screw to rotate through an external motor, the adjusting block can slide along the adjusting groove, and then the connecting rod can pull the T-shaped slider to slide along the T-shaped groove. As the T-shaped slider slides, the clamping plate will gradually rotate. By rotating the clamping plate, the fixed angle of the clamping plate can be adjusted, so that when the clamping plate fixes the cover with a non-linear edge, it can also fit well with its surface, making the clamping more stable. At the same time, by moving the first slider and the second slider, the distance between the four clamping components can be adjusted, and covers of various sizes can be fixed.

[0018] In this solution, the four corners of the cover are fixed by four clamping components, which reduces the contact area with the cover during fixation, leaves more welding space, can reduce the number of times of adjusting the position of the cover, and thus improves the welding efficiency.
